Pelargonium plant named ‘Kuegrarow’

ABSTRACT

A new and distinct cultivar of  Pelargonium  plant named ‘Kuegrarow’, characterized by its upright and mounding plant habit; freely branching habit; pinching is not required; freely flowering habit; large light pink and red purple bi-colored flowers; no requirement for cooling treatment for flower initiation and development; and good container and garden performance.

Botanical designation: Pelargonium crispum.

Cultivar denomination: ‘KUEGRAROW’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofPelargonium plant, botanically known as Pelargonium crispum andhereinafter referred to by the name ‘Kuegrarow’.

The new Pelargonium plant is a product of a planned breeding programconducted by the Inventors in Dresden, Germany. The objective of thebreeding program is to develop new Pelargonium crispum plants withuniform growth habit and unique flower colors.

The new Pelargonium plant originated from a cross-pollination made bythe Inventors in Dresden, Germany in 2008 of two unnamed proprietaryselections of Pelargonium crispum, not patented. The new Pelargoniumplant was discovered and selected by the Inventors as a single floweringplant from within the progeny of the stated cross-pollination in acontrolled greenhouse environment in Dresden, Germany in June, 2009.

Asexual reproduction of the new Pelargonium plant by vegetative terminalcuttings in a controlled greenhouse environment in Dresden, Germanysince August, 2009, has shown that the unique features of this newPelargonium plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Pelargonium have not been observed under all possibleenvironmental conditions and cultural conditions. The phenotype may varysomewhat with variations in environmental conditions such as temperatureand light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Kuegrarow’. These characteristics incombination distinguish ‘Kuegrarow’ as a new and distinct Pelargoniumplant:

-   -   1. Upright and mounding plant habit.    -   2. Freely branching habit; pinching is not required.    -   3. Freely flowering habit.    -   4. Large light pink and red purple bi-colored flowers.    -   5. No cooling treatment required for flower initiation and        development.    -   6. Good container and garden performance.

Plants of the new Pelargonium differ primarily from plants of the parentselections in flower color. In addition, plants of the new Pelargoniumare more freely branching than plants of the parent selections.

Plants of the new Pelargonium can be compared to plants of thePelargonium crispum ‘Cambi’, disclosed in U.S. Plant Pat. No. 20,426. Inside-by-side comparisons conducted in Dresden, Germany, plants of thenew Pelargonium differed from plants of ‘Cambi’ in the followingcharacteristics:

-   -   1. Plants of the new Pelargonium were more compact than plants        of ‘Cambi’.    -   2. Plants of the new Pelargonium flowered earlier than plants of        ‘Cambi’.    -   3. Plants of the new Pelargonium had larger flowers than plants        of ‘Cambi’.    -   4. Plants of the new Pelargonium and ‘Cambi’ differed in flower        color as plants of ‘Cambi’ had red purple and pale purple        bi-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Pelargonium plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Pelargonium plant. The photograph comprises a sideperspective view of a typical flowering plant of ‘Kuegrarow’ grown in acontainer.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the summer in 12-cm containersin a glass-covered greenhouse in Dresden, Germany and under culturalpractices which closely approximate commercial Pelargonium production.During the production of the plants, day and night temperatures averaged18° C. and light levels averaged 4,500 lux. Plants were 13 weeks oldwhen the photograph and the description were taken. In the detaileddescription, color references are made to The Royal HorticulturalSociety Colour Chart, 1995 Edition, except where general terms ofordinary dictionary significance are used.
